Specification of Letters Patent.

Patented June 29, 1909.

Application lcd January 2, 1909. Serial No. 470,834.

Be it known .that I, ALBERT I-I. CANFIELD, l a citizen of the United States, residing at l Bridgeport, county of Fairfield, State of; Connecticut, have invented a newand useful Reversible Valve for Flushingffanks, of

This invention relates te fioat valves adapted for general use ns in the flushing tanks of water-closets, and has for its object; to provide a reversible valve ot" this character that will be, sim le and inexpensive to use and will not become loose on the' 'rod l through the swirl of the water. l

With these and other objects in view I have devised the novel valve made alike atl both ends and both ends of which are adapted to be rigidly attached to the rod, which I will now describe, referring to the accompanying drawing forming a part of this specification and using reference characters to indicate the several parts.

Figure l is an elevation of my novel valve in place ona rod, and Fig. 2 is a vertical section thereof.

10 denotes the rod and 1l the valveI which is made of rubber, may beanade of any ordinary or preferred configuration, for exn :imple the configuration shown in the draw ing, and is preferably made alike at both ends. At each end' of the valve is a threaded spud or nut; `indicated by 12 which is tirmly seated in a hub ot rubber indicated by 12S. ',lhe rod passes entirely through the valve :from end to end and is threaded to engage both spuds. At. the lower end of the rod below the valve l place a nut 14 and a Set nut 15. 4

.lhethreaded spuds are molded into the hubs of rubber at the ends of the valve in the process of manufacture. In assembling, the rod 1s turned through both spuds and passes through the valve from end to end.

This operation may be perforincdby hand but is preferably performed mechanically. The nuts are then turned successively onto the projecting lower `end of therod. The. use of a nut and set nut anchors the valve securely on the rod and prevents it' from becoming loosened in use bythe swirl of the water. By giving to the valve a rigid attachment; at both ends -to the rod I effectuallyi prevent the valve from collapsing muse, my novel valves in practice wearing for an almost unlimited length of time.. In assembling-it makes no difl'erence which end et the fvalve is placed inward on the rod and should there be wear of the valve or seat (not shown) the valve may be readily reversed upon lthe rod and will be in fact n new valve.

Having thus described my invention I claim: l

1. A valve of the character described having a threaded Spud molded into each end.

and a rubber valve havingspuds in each end thereof through which the rod passes and a nut and set, nut at the end ot' the rod below the valve.

[n testimony whereof I eix my signature in presence o two witnesses.
